A man called his mother in Florida,
"Mom, how are you?"
" Not too good," said the mother. "I've been very weak."
The son said, "Why are you so weak?" She said, "Because I haven't
eaten in 38 days."
The son said, "That's terrible.
Why haven't you eaten in 38 days?"
The mother answered, "Because I didn't want my mouth to be filled with
food if you should call."
